Definitions

• the invention relates to a waterproofing membrane for building protection, which is waterproof and has a high tensile strength and flexibility.
• a sealing film for building protection which is used as a facade film (DE 200 23 324 U1), but is also used in the roof area, has a water and airtight thermoplastic or a composite material of plastic and aluminum foil as a central layer. Applied on both sides can be plastered outer layers of fleece, fabric, knitted fabrics, etc. These are also the substrates (substrates) that determine the tear strength and the desired elongation properties.
• a facade foil requires a particularly high tear resistance and flexibility, because it often has to be laid with tight radii of curvature. For this purpose, it preferably has a thickness of less than 1 mm.
• the basis weight of the base layer (s) is between 20 g / m 2 and 300 g / m 2
• the basis weight of the plastic coating is 20 g / m 2 to 250 g / m 2 , preferably about 80 g / m 2 up to 130 g / m 2 .
• the total basis weight is preferably about 300 g / m 2 . If it can be plastered over, as described in DE 200 20 324 U1, it must also be able to carry the cleaning weight and be able to hold the plaster adhering. Moreover, a sealing film must be able to be glued as a facade film on the masonry and / or on Novaleibache.
• sealing foils for building protection in particular for use as a facade foil, there are currently only products of building material class B2 "normally flammable". Increasing the proportion of chemical flame retardants in such sealing films, the sealing film loses some of its flexibility, it is stiffer, the coating is more brittle. For thin, very flexible films you need additional plasticizers. These affect the flame retardancy.
• Another known sealing film for building protection which is waterproof and has a high tensile strength and flexibility (DE 196 09 311 A1), expressly takes into account aspects of fire protection. It meets the building material class B2 of DIN 4102 with a woven, knitted or non-woven textile support material as a support layer and a one-sided or double-sided applied coating, which is used as an aqueous dispersion with a viscosity of up to
• aqueous dispersion contains up to 30% by weight of a flame retardant.
• Basis of this dispersion is a suitably adjusted polyurethane with up to 60 wt .-%.
• Suitable chemical flame retardants are given in DE 196 09 311 A1. All other components are described in detail and with examples. Polyethylene, polypropylene, polyester and glass fibers are specified for the carrier material forming the base layer, which are particularly preferably processed into nonwovens having a weight per unit area of 50 to 300 g / m 2 .

• sealing film for building protection is not taken into account the specifics that are important for facade films. In particular, these are over plasterability of the sealing film and bondability to masonry and window reveals.
• the invention is now based on the problem of specifying a sealing film which achieves the highest possible fire resistance class, in particular the building material class B1 "flame retardant" or reaches an even higher level of fire protection and nonetheless can also be used as a facade film.
• the coating which has been applied as an aqueous dispersion to the base layer and dried thereon also forms the outer surface of the sealing film in the case of the sealing film according to the invention.
• the coating used in the sealing film according to the invention has a considerable amount of non-combustible, solid inorganic fillers, in particular non-combustible inorganic Fibers on.
• glass fibers It is a highly elastic, very flexible coating, which does not tear even in a larger layer thickness and the sealing film affects only slightly in their flexibility.
• the non-combustible, solid inorganic fillers results in a significantly increased fire resistance, so that a high fire resistance class of z. B. F 60 to F 90 is achieved.
• building material class B1 "hardly inflammable" is easily achieved for the sealing film. Possibly. even an overlying building material class of fire protection is achieved.
• the fire resistance class which is achieved according to the invention is determined according to DIN 4102-2 also to the effect that a fire transmission over the building material for the predetermined time is prevented. In this regard, a slight foaming of the coating material under the action of heat can be helpful.
• the non-combustible solid inorganic fillers provide a comparatively rough surface of the coating.
• This makes it possible for this sealing foil to be plastered over like a classic facade foil and also adhesively bonded to the masonry and / or to window revealings. Plaster and adhesive find sufficient support on the rough surface.
• plaster in the sense of the present patent application can be understood hydraulically setting mortar systems based on cement and / or lime cement, but also gypsum or anhydrite, etc., as they are common in interior and exterior plasters, Ansetzbindern.
• the carrier material forming the base layer is either a material which is permeable to water vapor, in particular a nonwoven fabric, a woven fabric, a knitted fabric or a scrim, in particular made of synthetic fibers or glass fibers, or a material which is diffusion-tight or diffusion-inhibiting for water vapor, in particular a plastic film or a metal foil is.
• a metal foil for example an aluminum foil, itself already corresponds to the building material class A.
• the other materials are influenced by a conventional chemical flame retardant, which does not unduly impair their flexibility, in the direction of independent flame retardancy, so that overall the sealing film including these special support layers a high Building material class of fire protection according to DIN 4102-1 achieved.
• this sealing film for building protection which is also determined and suitable as a facade film, results in the desired flexibility and manageability under site conditions with a structure that is similar to the structure of the sealing film of the starting point for teaching (DE 200 23 324 U1).
• the base layer is arranged on the outside. So it brings home already the necessary over plasterability and adhesion for plaster and adhesives, which is already given at the starting point for the teaching of the present invention.
• the building material class B1 "flame retardant" or even an even higher building material class of fire protection is achieved in that a certain composition of the occurring here as a separate film coating is selected.
• This composition is specified in claim 9.
• the base layer forming nonwoven fabric, woven, knitted or scrim on the basis of glass fibers and / or acrylic fibers itself is already equipped fire-retardant.
• the outer nonwoven fabric, woven, knitted fabric or scrim even if it is formed from glass fibers and / or acrylic fibers, forms heat esters on the surface of the PVC-based film-like coating.
• the nonwoven, woven fabric, knitted fabric or scrim if it is itself partially flamed, acts as a fire accelerator for the film-like coating based on PVC.
• This function takes according to the invention the fleece, fabric, knitted fabric or scrim by the there already carried out by home equipment with a flame retardant, so that this fleece, fabric, knitted fabric or scrims already meets the building material class B1 "flame retardant".
• the proportion of plasticizer based on polyaddipate is reduced and instead a chlorinated polyethylene is added.
• This polyethylene is modified so that it also has a fire retardant effect in addition to the plasticizing effect for the PVC.
